Scientific Method

1.Q - What's the difference between a rock and a mineral?
2. First, you need to add table salt to the water. Later, it will be evaporated and you will see the results
3.HYPOTHESIS - The water might become a mineral, either quartz or a halite crystal structure.
4.What are rocks/minerals? - Take all the rocks and organize based on rock or mineral
mineral rock
crystal not shiny
one substance different colors
more than one substance
5.MATERIALS -
4 magnifying glasses
2 Popsicle sticks Salt + Water = CRYSTALS
1 piece of tape
1 tray
1 plate
6. PROCEDURE -
Before - Boil water CAUTION: HOT!
First pour water and salt in the bottom of both of your cups and stir for a minute. Then pour 2/3 of it on both spoons which are taped on plate. Write your name on the masc in tape .
On the second day look for results on spoon (crystals)
Crystal- a mineral formation with a geometric pattern when elements and molecules come together.
